On January 1, 2020, Metlock Co. borrowed and received $240,000 from a major customer evidenced by a zero-interest-bearing note due in 4 years. As consideration for the zero-interest-bearing feature, Metlock agrees to supply the customer's inventory needs for the loan period at lower than the market price. The appropriate rate at which to impute interest is 9%. (a) Prepare the journal entry to record the initial transaction on January 1, 2020.
